Just Say N20

A unique opportunity to purchase a “long block plus” 350 Marine engine.
This engine was built as part of the restoration of a 1967 Donzi Ski-Sporter 16, which is documented on this site ( http://www.donzi.net/forums/showthread.php?58186-Deck-is-off&highlight=Deck+is+off ). I have included pictures of the completed project so you can appreciate the overwhelming attention to detail demonstrated by this project. The engine received the same attention.
The engine was broken in properly, and the initial oil/filter changed at 14 hours. The engine now has 51 hours of fresh water only run time on it. There is a video of the engine running at the end of this post.
The carb (Holley 715 CFM 4bbl, single pump, vacuum secondary’s) was re-jetted for this application, but I have not replaced the secondary spring. In the video, you can hear a hesitation in the video when the throttle is opened completely. I believe the current spring is too strong.
The engine runs strong up to 5,000 rpms (Volvo A290 outdrive w/1.61 ratio, spinning a 14’ X 24” Volvo Ultra S/S prop).
This engine was completely rebuilt by the Grand Rapids, Michigan NAPA machine shop. It was bored 030 over and the crank was mildly polished. Following is a partial list of what the engine received:
• Rebuilt heads (194)
• New Pistons/Rings/Bearings
• New Oil pump
• New Oil pan
• New Water recirculation pump
• New camshaft (Melling Select #22124)
• New Cam Chain Cover
• New Chrome Valve covers
While I realize I could sell this as a long block, and then sell the carb, intake manifold and exhaust manifolds/risers separately and make more money, I have decided to sell the engine as a long-block+. In addition to a rebuilt block, new camshaft & rebuilt heads, I am going to include the additional items currently on the engine:
• Intake manifold, GM dual plane
• Carb, Holley 715 CFM 4bb
• Exhaust Manifolds, OSCO center riser
• Valve covers
The following items are NOT INCLUDED:
• Starter
• Alternator
• Crank mounted water pump
• Ignition/Distributor
• Wire harness
• Remote oil filter kit
Asking $2,250.
